Thanks for the responses, DeafAudi, AutismAdvocate, sayjo, arthritiskid, and SLPamy!
sayjo, I got an e-mail from Elmhurst last Thursday with an electronic version of the letter that was sent in the mail, which I expect to receive tomorrow.
arthritiskid, I was more nervous and prepared than I needed to be for the Midwestern interview. It's really not bad. Yes, there is pressure to stand out, but remember they're also trying to impress you. Come with questions, an open mind, and confidence.
SLPamy, I also think it was a last minute decision by Elmhurst to do interviews. Guess I'll be seeing you on Friday!
